DOOR HANDLE ASSEMBLY Filed Sept.. 19, 1938 INVENTOR WILLIAM OQDEVEREAUXI ATTORNEY Patented Apr. 30, 1940 UNITED STATES PATENT OFFICE" 11Claims.

This invention deals with door handle assemblies and more especiallydoor handle assemblies having provision for locking the door handleshank firmly in place in the body of the door.

One of the objects of this invention is to provide a door handlestructure composed of a plu- 'rality of parts capable of being readilyassembled and locked in place in the door. A further object of thisinvention is to provide a door handle assembly having a positive lockingmeans for the handle of a simple and inexpensive design.

With these and other objects in View, the invention resides in certainnovel features of construction, combinations and arrangements of partsas will be more fully described and particularly pointed out in theappended claims. With reference to the drawing:

I With reference to Figure 1, it will be seen that the invention dealswith adoor-handle such as I 0 having a shank H extending through theouter panel P2 of the door as well as through an escutcheon plate l3 onthe exterior side of the door I2. Shank ll extends to the inner side Mof the door and is maintained in place through vention resides in theconstruction of the mounting cup and clip in a manner to firmly locktheshank ll in place inside the door body, which in turn assures properlocation of the handle ID with relation to the escutcheon plate l3 andthe outer panel of the door.

With reference to the invention more in detail, wherein like referencecharacters indicate like parts, it will be 'seen that the door panel I2is provided with an opening ll through which shank may pass; On theinner side of panel l2 and surrounding this opening is a mounting cup16. This cup isformed from a sheet metal stamping and has attachedportions l8 extending laterally therefrom to provide'for attaching thecup inside of the, panel l2 by welding or the like. The bottom IQ of thecup is provi'dedwith an opening 20 in alignment with opening I i in thedoor through which the shank. H may also be extended.

The cup, as shown, is provided with an annular side wall having openings2 I in diametrically op-' posite sides and having lugs 22 extendinginwardly therefrom between the openings 2!. In the present instance thelugs are struck inwardly from the side wall of the cup. The cup ismounted on the door in a manner so as to have one of the openings 2|facing the swinging edge of the'door. stantially right angles to theopenings 2!. The lugs 22 are designed so that the, free edges 23 are,spaced a sufficient distance from the ad.- jacent surface l9 of the cupto allow the leg 29 of the clip [5 to slide between the edges 23 of thelugs and the surface [9 of the cup.

Shank II is rectangular in cross section and has one end permanentlysecured within the end 24 of the handle H] in any suitable manner. Asstated above, the shank is maintained in place in the door by the springclip I5. This clip is formed of two substantially V-shaped sheet metalmembers 25 and 26 identical except that the dimensions are so determinedas to permit nesting the me'mbersj Both legs 28 and 29 of the clip haveopenings 31] therein of suflicient dimension to allow the shank to pass'therethrough when the legs are compressed to dispose the openings inparallel relationship to one another. Upon reference to Figure 3 it willbe noted that the diametrically opposite sides of openings 30 on thelegs of ,the clip are fashioned to form lips adapted to, have a'bitingengagement with the adjacent sides of the shank when the pressure isreleased from the clip and the legs returned to their normal angularlyrelated positions. It will be noticed that by providing two V-shapedsheet metal members 25 and 26 instead of one that additional efiiciencyis created. Instead of having two sets of lips 45 effecting' a bitingengagement with the shank, actually there are four sets of lips. Notonly is the wedging effect increased by the use of a clip in two partsinstead of one, but also if one of the clips fails to function properlythe locking effect of the remaining clip will be present.

After the clip is initially placed on the shank, the'shank is insertedinto the door and rotated to effect locking of the clip with the cup.This is accomplished in the present instance by providing a lower leg 29of the clip with two notches This will place the lugs 22 at sub-' 3| ofsuflicient size to allow the clip to slide over handle having a shankadapted to be inserted in a door, a spring clip mounted on the shankto'form a unit with the latter and frictionally secured to the shank toprevent relative axial movement between the shank and clip, and

means carried by the door and cooperating with the clip to secure theshank in assembled relation with the door.

7. In a door handle assembly, an operating handle having a shank adaptedto be inserted in a door, a spring clip mounted on the shank to form aunit with the latter and frictionally secured to the shank topreventrelative axial movement between the shank and clip, and means carried bythe door and responsive to rocking movement of the shank and clip toengage the clip and prevent unauthorized withdrawal of the shank fromthe door.

8. In a door handle assembly, an-op'erating handle having a shankadapted to be inserted in the door, a clip having a portion apertured tofreely receive the shank and normally urged to a position angularlydisposed with respect to a plane perpendicular to the axis of the shaftto frictionally engage opposite edges of the opening with theadjacentsides of the shank and thereby lock the shank against axial movementrelative to the clip, and means carried by the door and responsive torocking movement of the shank and clip to engage the clip and preventwithdrawal of the shank from the door.

9. In a door handle assembly, an operating handle having a shank adaptedto be inserted in the door, a clip having a portion apertured to freelyreceive the shank and normally urged to a position angularly disposedwith respect to a plane'perpendicular to the axis of the shaft tofrictionally engage opposite edges of the opening with the adjacentsides of the shank and thereby lock the shank against axial movementrelative to the clip, a cup-shaped member carried by the door'forming ahousing for the clip and having a projection responsive to rockingmovement of the shank and clip to engage the clip and prevent withdrawalof the shank from the door.

10. In a door handle assembly, an operating handle having ashank'adapted to be inserted in a door, a spring clip mounted on theshank to form a unit with the latter and frictionally secured to theshank to prevent relative axial movement between the shank and clip, acupshaped member carried by the door and adapted to house the clip, andprojections on the cupshaped member efiective upon rocking movement ofthe shank and clip to engage said. clip and prevent withdrawal ofthe'shank from the door.

.11. Ina door handle assembly, an operating handle having ashank'adapted to be inserted in a door, a spring clip having divergingsides provided with openings therethrough dimensioned to freely receivethe shank when the sides of the clip are flexed to a position whereinsaid sides are substantially parallel to one another, the opening in oneside having an edge portion arranged to fixedly grip the shank in theangular position of the sides to prevent relative axial movement of theshank and clip, a cup-shaped member carried by the door and adapted tohouse the clip, and projections on the cup-shaped member responsive torocking movement of the shank and clip to engage one 01' the sides ofthe clip and prevent axial displacement of the shank relative to thedoor. v
